Hello, i need to implement a project able to read data from a register and send them to the pc via ethernet. i've watched the demo 'IwIp Echo Server', but i can't understand how it can receive and send data. i think this function (shown as attachment) must be in the 'while(1)', but watching these functions i can't find anything that seems to actually send or receive data. I wanted to know if you can actually read a register via ethernet port(and print to Tera Term terminal) and if there is a function or set of functions created for this purpose(i.e. write and read to a register) like for the Uart port. i searched around a lot but couldn't find enough information. i am using vivado sdk 2016.4 and am on a microblaze system.
